SPECIFICATION forming part of Letters Patent No. 496,448, dated May 2,1893.

Application iiled August 1'7J 1891.

To all whom it may concern:

' Be it known that I, WASHINGTON L. Sco- VILLE, a citizen of the UnitedStates, residing at Chicago, in the county ofV Cook and State ofIllinois, have invented certain new and useful Improvements inCan-Openers, of which the following is a full, clear, and exactdescription, that will enablerothers to make and use the same, referencebeing had to the accompanying drawings, forming a part of thisspecification, in which- Figurel is a plan; Fig. 2 the reverse of Fig.1; Fig. 3 a detached detail of the cuttingblade and holder; and Fig. 4 abroken-away section on line 4 Fig. 2.

This invention relates to improvements in can-openers, and has for itsobject to provide a device of this character that is more especiallyintended for use on cans other than those of a cylindrical form, such assardine Referring to the drawings, A represents an elongated framehaving the handle part B formed integral therewith. This frame is of acontour corresponding to that of a sardine can, the frame and handlepart consisting of a single casting. The inner end of the fixed handleBis provided on the upper side with the pivot-pin a., (Fig. 1,) whichsecures the movable handle-member C to the companion member. Thehandle-member C is provided in its inner -end with the elongated slot athrough which the connecting pivot joint pin projects, the projectingend ot' said pin being screw threaded for the engagement of the thumbholding or clamping-nut a2, as shown in Fig. l. Ordinarily theclamping-nut will be set loosely so that the handle C will have anendwise movement and provide for an automatic adjustment in followingthe contour of the frame part in the operation of opening a can.

The cutting-blade holder or plate D is set in the upper side of theframeAand secured to the carrying-handle C by the pivot-pin a3, insertedin the aperture a4, which permits the holder to adjust itself andconform to the frame as it is caused to traverse the same.

serted in the under side of the carrying-handle; the lower end passingunderneath and having loose contact with the under side of the framepart and assisting in retaining the holder in proper position. The underside of the frame is also provided with a number of downwardlyprojecting lugs d, which are adapted to bear against the edge of the canand retain the frame in place during the operation. The 'prick-points cld can be forced into the metal and also assist in holding the vframe inplace.

The frame may be of any desired shape so as to correspond to the contourof any particular class of cans. The dotted lines indicate the relativeposition of the can.

This arrangment provides a device by means of which, sardine cans maybeopened with the greatest ease and facility.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a can-opener, the combination with a frame and integralhandle-member, of the companion handle-member, provided with anelongated slot and secured to the integral handle by a pivot-pin passingthrough said slot, and the holder, loosely seated upon said frame andpivoted to the slotted handle, whereby said slotted handle is adapted tohave an automatic endwise adjustment to conform to the contour of theframe part, substantially as and for the purpose described.

2. In a can-opener, the combination with the frame, of the movablehandle-member, having an automatic endwise adjustment on its pivot, theholder, seated on said frame and pivoted to said handle-member, thecuttingblade, fixed in said holder and projecting down along the inneredge of said frame, and the guide-pins, inserted in the outer cornersIOO of the holder and engaging with the eorreloosely secured to themovable handle, and spending edge of said fra1ne,snbstantially as theguide-linger, inserted in said handle and ro and for the purpose setforth. bearing against the underside of said frame,
